6) In the Figure 5, monochromatic light from a sodium lamp (A = 589 nm) is shone on a soap bubble thin film from the same side you are viewing the film. For the first four bands (band one being yellow, two black...), what are possible thicknesses of the film? Note: You would need to research some indices of refraction.
